I like to hear a drummer that can play the double bass at varying tempos. Vader's drummer and of course Pete Sandoval of Morbid Angel are awesome on the double bass. "Opening of the gates" by morbid angel has the fastest double bass beat ever under the chorus. Derek Roddy is also quite good on the double bass, i read an interview with him and it said he can hit 260 bpm with single stroke bass hits.
